Ground Pine
or Clubmoss, a mossy, trailing evergreen plant of deep woods. It is allied to the ferns. There are 100 different kinds. The dusty spores are sold as lycopodium powder by druggists. It kills cockroaches and many other insects. It is almost as inflammable as gunpowder. Ground pine is in demand for Christmas decorations. It keeps well, and is usually gathered during the long Indian summer of the North from Minnesota to Maine, and shipped to market in barrels or boxes. Wisconsin, it is said, ships thirty-five carloads a year.
